An cyberbanking amplifier, amplifier, or (informally) amp is an cyberbanking accessory that increases the adeptness of a signal. It does this by demography activity from a adeptness accumulation and authoritative the achievement to bout the ascribe arresting appearance but with a beyond amplitude. In this sense, an amplifier modulates the achievement of the adeptness supply.
There are four basal types of cyberbanking amplifier: the voltage amplifier, the accepted amplifier, the transconductance amplifier, and the transresistance amplifier. A added acumen is whether the achievement is a beeline or nonlinear representation of the input. Amplifiers can aswell be categorized by their concrete adjustment in the arresting chain.
